I am 20 year old boy. On 13/11/2012, I met a 30 year old man accidentally. I did not know his status about HIV infection. We had open mouth kissing each other. I did not have any mouth ulcers at that time but I did not know whether I had minute bleeding in between my teeth. I did not know whether that man had mouth ulcers or bleeding gums. Then he rubbed his penis on my anal opening and applied some pressure. But I am sure that he did not penetrated and he did not ejaculated at that time. He asked me to do the same and I too did not penetrated and ejaculated.
Then he masturbated me and himself. That's it.
My question is that if that person is HIV positive and if he had mouth sores at that time, what is the chance for me to get infected with HIV??
I did not know at that time that this act will bring me this mouth trouble. On the next day only I came to know that gays are more predominant for HIV infection.
If I had known it before, I would not have allowed him to do so.
Please clarify my doubt as soon as possible. Thank you in advance for your quick reply.
